Conversion of succinic acid over Ni and Co catalysts
(Elsevier B.V., 2020)
Supercritical hydrogenation processes experimental results on the fluid phase behavior of binary and ternary mixtures of hydrogen, propane and tripalmitin
(Elsevier Science, 2003-03-17)
The problems of low reaction rate and cis-trans isomerization encountered in the gas-liquid catalyzed hydrogenation of vegetable oils can be overcome by using a supercritical fluid to bring the reactive mixture into a ...
Hydrogen and energy savings using heuristic allocation of mass exchangers in process synthesis: Technical analysis
(Pergamon-Elsevier Science Ltd, 2019-05-21)
For our works, Mass Exchangers (MEs) are membrane equipment that exchange some component between two streams in a countercurrent arrangement. In previous works these were proposed to use them (with the goal of hydrogen ...
Niobium hydrogenation process Effect of temperature and cooling rate from the hydrogenation temperature
(ELSEVIER SCI LTD, 2011)
High-purity niobium powder can be produced via the hydrogenation and dehydrogenation processes The present work aimed at the effect of temperature and cooling rate conditions on the niobium hydrogenation process using ...
Analysis of the Effect of Surface Hydrogen Concentration on the Hydrogen Oxidation Reaction: Voltammetry vs. Steady State
(Research Trends, 2017-07)
Starting from the modelling of the processes involved in the hydrogen oxidation reaction, the present work provides an explanation about the origin of the differences observed between the polarization curves obtained by ...
Prediction via neural networks of the residual hydrogen peroxide used in photo-fenton processes for effluent treatment
(Wiley-Blackwell, 2007-08-01)
This communication proposes the use of neural networks in the prediction of residual concentrations of hydrogen peroxide from the treatment of effluents through Advanced Oxidative Processes (AOP's), in particular, the ...

Performance of the catalytic membrane reactors of different pore size with palladium as catalytic phase in hydrogenation and oxidation reactions
(2018)
The catalytic membrane reactors (CMR) were prepared using a commercial Hollow Fiber Membrane of corundum of 4 and 1400 nm and impregnated palladium. The tests performed were phenol hydrogenation, hydrogen peroxide generation ...
Hydrogen recovery from the purge stream of a cyclohexane production process using a mass exchange heuristic
(Pergamon-Elsevier Science Ltd, 2014-12)
In this paper, we propose a novel hydrogen recovery structure in a cyclohexane production process, arrived at by following a mass exchange heuristic developed in previous works [1,2]. In the cyclohexane production process ...
Characterization of Nanocomposites for Hydrogen Storage
(Amer Inst Physics, 2017)
The use of hydrogen as an energy carrier suitable to replace gasoline and other fossil fuels has been widely discussed as a way to sustainably fuel our civilization. However, hydrogen storage is a major harrier in the ...
